Description
This function is used to configure the calling number (CLIP) sent to correspondents on outgoing ISDN
calls. For example, it enables a company with several sites always to send the same number to external
called parties.
On an outgoing external call, the number transmitted is:
- the installation number completed by the DDI number of the caller (or the Operator Group num-
ber), if the "Alternative CLIP number" is not configured.
- the "Alternative CLIP number", if configured.
